What are the consequences of mixing different colors of coolant?

[TuckerLee]

Mixing different colors of coolant may cause a chemical reaction, leading to the coolant losing its effectiveness and failing to adequately protect the engine, potentially causing other adverse effects. Coolant replacement cycle: Vehicle coolant generally needs to be replaced every 2 years or 40,000 kilometers. This is just a reference period. For commercial vehicles with higher mileage, the replacement cycle should be shorter. Since driving conditions vary for each vehicle, the replacement should be based on actual usage. Check the coolant's condition regularly. If the coolant level is low, replenish it promptly. If suspended particles, sediment, or signs of deterioration or discoloration are observed in the coolant, replace it immediately and clean the system. How to choose coolant: The basic indicators of coolant are freezing point and boiling point. On the market, coolants are available with freezing points of -15°C, -25°C, -30°C, -40°C, etc. Generally, it is advisable to choose a coolant with a freezing point at least 10°C lower than the lowest temperature in your region.
